TAN K-HEATER.

SPECIFICATION forming part of Letters Patent No. 613,837, dated November 8, 1898.

Application filed January 8, 1898- Serial No. 666,079. (No model.)

To all whom it may concern.-

Be it known that I, WILBER R. DUNKEL, of Harristowu, in the county of Macon and State of Illinois, have invented certain new and useful Improvements in Tank-Heaters, of which the following is a specification.

This invention relates to heaters used in stock-watering tanks. unit the safe and economical use of hydrocarbons, as gasolene. It is exemplified in the structure hereinafter described and it is defined in the appended claims.

In the drawings forming part of this specification, Figure 1 is a perspective representation of a tank-heater embodying my improvements. Fig. 2 is a plan of the top of the Fig. 3 is a vertical section through the heater, showing the relation of the heater to the tank.

The body of the heater consists of a horizontal heat-chamber 2, adapted to rest on the bottom of the tank below the surface of the water therein, and a vertical chamber 1, communicating with a side of the heat-chamher and rising above the surface of the water in the tank. A plate 5 extends horizontally from the upper end of the vertical chamber 1 in a manner to coincide With the horizontal outline of the heat-chamber, and ventilationpipes 3 and 4 extend from the side of the heat-chamber opposite the vertical chamber 1 upward through plate 5. A tank 13 for gasolene or other hydrocarbon sits on plate 5 with one of its sides projecting over the vertical chamber 1, and from its bottom surface a pipe extends downward throughthe vertical chamber and sidewise into the heatchamber, where it connects with a vaporburner. The vertical extension of the pipe is shown at 15, the horizontal extension at 16, and at 14 is shown a vapor-burner.

At 17 is shown a valve by means of which flow of fuel from the tank 13 may be controlled.

A flap 6 is adapted to cover the upper end of the vertical chamber. It is preferably hinged to the side thereof opposite the fueltank. It has corner extensions 6, which are adapted to embrace the sides of the fuel-tank and hold it in position on plate 5, and it has openings, as 6 which correspond in area with the area of the ends of pipes 3 and 4. In Fig.

It is designed to per 2 the flap 6 is shown swung away from the f uel-tank and from over the vertical chamber.

A storm-hood 7 is shaped to cover plate 5 and the fuel-tank thereon. It is preferably hinged to a side of the plate, and it may have a lug 10, which will extend through a slot 11 in plate 5 and provide for fastening the hood closed. The roof 8 of the hood is arched, and its eaves project beyond and below the upper edges of the sides. Under the eaves the sides are cut away, as shown at 9, to provide for circulationof air, while excluding rain or snow. 1

Straps, as 12, are fastened to the inner wall of the Vertical chamber in a manner to form loops, and when the heater is placedin the water-tank, which is represented at 19 in Fig. 3, a scantling, as 18, is extended through the loops and fastened at its .ends to the sides of the water-tank. The function of the scantling is to hold the heat-chamber of the heater submerged and keep the heater in proper position in the tank.

The gasolene-burner and fuel-tank are detachable from the heater, and in starting the heater the burner is lighted outside the heater and properly regulated. It is then lowered through the vertical chamber with the horizontal portion of its pipe lengthwise of the opening therein, the burner is swunginto the heat-chamber, the fuel-tank is seated on plate 5, the flap 6 is swung into position to cover the vertical chamber and embrace the sides of the fuel-tank, and the storm-hood is closed. The heat of the burner is applied to the upper surface of the heat-chamber underneath the water and is used in the most economical way possible. Air is supplied to the burner through the openings 6" and tubes 3 at in an equable manner and without any tendency to divert the heat of the burner from the horizontal surface of the heat chamber. The storm-hood covers all openings leading to the burner, and it is ventilated in a manner to exclude snow or rain and to moderate strong winds. Consequently the burner cannot be affected by the elements.

WVhile a single vapor burner will furnish sufficient heat to supply a water-tank of moderate size, there is no difficulty attending the use of more than one burner in a single heatchamber. W'hen that is done, theheat-chamher should be enlarged to increase submerged heating-surface and the extension can be made in any desired direction from the vertical chamber. \Vhen more than one burner is used, each may have a separate fuel-tank and supply-pipe or all may connect with the one tank.

\Vhat I claim is 1. In a tank-heater, the combination of a body consisting of a horizontal chamber and a vertical chamber rising from one side of the horizontal chamber, a pipe, or pipes, rising from the horizontal chamber on the side opposite the vertical chamber, a horizontal plate in which the pipes and the vertical chamber terminate, a hydr0carbon-tank seated on the plate, a removable flap covering the vertical chamber and embracing the tank, such flap having openings for air passage, a hydrocarbon-burner in the horizontal chamber and a pipe connecting the tank with the burner, substantially as set forth.

2. In a tank-heater, the combination of a body consisting of a horizontal chamber and a vertical chamber rising from one side of the horizontal chamber, a pipe, or pipes, rising from the horizontal chamber on the side opposite the vertical chamber, a horizontal plate in which the pipes and the vertical chamber terminate, a hydrocarbon-tank seated on the plate, a removable flap covering the vertical chamber and embracing the tank, such flap having openings for air passage, a hydrocarbon-burner in the horizontal chamber, a pipe connecting the tank with the burner and a storm-hood adapted to cover the plate and the hydrocarbon -tank thereon, such hood having protected air-openings substantially as set forth.

In testimony whereof I sign my name in the presence of two subscribing Witnesses.
